Use observed rates where possible
Your own fuel-per-boil, food-per-day, device use or water-consumption observations are more useful than treating a generic average as a personal requirement.
Do the trip arithmetic before the trailhead.
Turn route time, food, fuel, power, water capacity and emergency details into a plan you can review before leaving. The calculators use the numbers you enter and are built for preparation rather than live navigation or safety guarantees.
Add a reserve deliberately
A planning buffer should be visible rather than hidden inside a guess. Stress-test the plan against delays, weather and an extra day where the tool supports it.
Keep critical plans shareable
For paddling and remote trips, leave the route, party and overdue/check-in details with someone who is not on the trip when appropriate.

Choose the question you need to answer.
Outdoor tools are planning aids, not navigation, rescue, weather, diving, medical or hydration advice. Conditions change. Verify route access, forecasts, regulations, equipment limits and safety requirements with appropriate authoritative sources.
